An elbow joint strain is a common disease in orthopaedic surgeries, and it is characterized by elbow soreness and pain caused by non-acute injury. Its pathology mainly includes lateral epicondylitis, medial epicondylitis, olecranon bursitis, and so on. Common causes of elbow joint strain are long-term improper posture, excessive use of the elbow joint or trauma, such as hit on the elbow joint. Conservative treatment 1s still considered as the mainstay of treatment of such disease. It mainly comprises closed-up needle injection and follow-up physiotherapy rehabilitation. Of note, continuous physiotherapy is particularly important, which has advantages of non-invasive, non-traumatic, continuous curative effects and prevention of elbow joint strain recurrence.

In such case, patients usually use traditional physiotherapy instruments instead. However, the traditional physiotherapy instruments are not designed for elbow joint physiotherapy, and the wearing experience 1s poor. Moreover, the traditional physiotherapy mstruments generally use heating resistance wires, which have poor heating effect and are difficult to achieve an intelligent control of temperature.

Graphene has extraordinary heat conductivity properties. Îts total effective conversion rate of electrical and thermal energy is over 99%. The superconductivity of the special graphene ensures stable heating performance. Graphene heating pads and other products are available now in the market. Such products use graphene instead of traditional resistance wires for heating, which 1s more practical.

9 LU502025 invention will now be described more fully hereinafter with reference to the accompanying drawings and exemplary embodiments, however, the invention is not limited thereto.
As shown in Figures 1 to 3, the invention provides a graphene physiotherapy elbow pad, comprising a high-elastic elbow pad body 10, a retractable heating module 20 and a temperature control module 30. The graphene physiotherapy elbow pad body 10 comprises a surface layer 11, a middle layer 13, and an inner layer 12, wherein the inner layer 12 is a layer which is in contact with skin. The surface layer 11 and the inner layer 12 are an integral structure, and a hollow structure, that is, the middle layer 13, is formed between the surface layer 11 and the inner layer 12, and the retractable heating module 20 and the temperature control module 30 are both arranged in the middle layer.
The surface layer 11 and the inner layer 12 were three-dimensionally woven from polyurethane nanofibers and have elasticity. The polyurethane nanofibers used in the present invention were prepared by the following method: the polyurethane nanofibers were prepared with an electrospimning equipment
SS-2535H, Ucalery . Tetrahydrofuran and N,N-dimethylformamide were used as a solvent, and polyurethane (10514005, WEICON) was dissolved in the solvent at a ratio of 3:1 to prepare a 10% polyurethane solution. The prepared 10% polyurethane solution was stirred at 800 rpm for 48 hours with a magnetic stirrer (81-2, Shanghai Sile Instruments Co, Ltd.) to prepare a well-mixed suspension.
10 LU502025
Then electrospinning was performed at a room temperature of 24°C with a voltage of 12 kV was applied, a recetving distance of 13 om, a spinning solution flow rate of 0.3 mm/min. Finally, polyurethane nanofiber membranes were prepared after the electrospinning process was carried out for 6 hours. The nanofiber membranes were cut into pieces with a size of lem X lem using a cutting die. The pieces were added to a beaker containing 100ml of tert-butanol, and the nanofiber membranes were smashed by a high-speed homogenizer at 12,000 rpm for 15 minutes. The solution was introduced into a cylindrical mold with a diameter of 3 mm, and a length of 35 cm, and the cylindrical mold 19 containing the solution was placed in a freezer dryer for 48 hours until it was completely lvophilized. Next, it was soaked in glutaraldehyde for 10 minutes for cross-linking. It was rinsed with deionized water, and then lyophilized for 48 hours to obtain a 3D nanofiber woven material for three-dimensionally weaving the high-elastic elbow pad body 10. The polyurethane fiber prepared by the above preparation method had a nanostructure, so that the high-elastic elbow pad body 10 prepared by weaving had better elasticity.
As shown m Figure 4, a retractable heating module 20 can be configured to perform a heating physiotherapy on an elbow. It comprises a plurality of graphene heating filaments 21, a plurality of elastic members 22, a first control unit 23, and a first power supply 24. Each of the plurality of elastic members 22 is an ultra-fine spring metal wire, which was coiled in a “Z” shape and is stretched and elongated. The plurality of graphene heating filaments 21 are bent
1 LU502025 and surround the ultra-fine spring metal wire; the plurality of graphene heating filaments are provided with a plurality of fixed points, the plurality of fixed points are bonded and fixed to a middle point between corners of the “Z” shape formed by the ultra-fine spring metal wire by using polytetrafluorcethylene. In this way, the graphene heating filaments 21 can be bonded to and cross-linked with the elastic members 22. The plurality of graphene heating filaments can be stretched and retracted accompanying with the extension and flexion of the elastic members 22. When the graphene physiotherapy elbow pad is worn on the elbow, since the elbow is a curved surface, the graphene physiotherapy elbow 19 pad will be flexed and deformed when the arm is flexed and stretched. Since the plurality of graphene heating filaments 21 can be flexed and deformed accompanying with the extension and flexion of the plurality of elastic members 22, the heating function of the retractable heating module 20 may not be affected when the elbow pad is flexed and deformed. In addition, a patient does not have to keep the arm stretched all the time when he/she uses the graphene physiotherapy elbow pad provided by the present invention, which brings the patient a comfortable experience.

3 LU502025 detection components 31 detect temperature information in the graphene physiotherapy elbow pad and send the detected temperature information to the analog-to-digital conversion unit 32 for converting into a signal, and send the converted signal to the second control power supply 33. The temperature information corresponding to the signal is compared with a preset temperature interval. For example, the temperature interval may be 37°C-39°C. If the temperature is less than 37°C, the second control unit 33 sends a control signal to the first control unit 23 to activate the graphene heating filaments 21 for heating. If the temperature is greater than 39°C, the second control unit 33 sends 19 a control signal to the first control unit 23, so that it stops heating of the graphene heating filaments 21 to cool down, thereby avoiding overheating of the retractable heating module 20. If the temperature is excessively high, the patient may feel uncomfortable, and thus the effects of the physiotherapy cannot be achieved as expected.
The middle layer may comprise a plurality of compartments, each of the plurality of compartments is provided with a graphene heating filament 21, an elastic member 22 and a temperature detection component 31, respectively.
The heating physiotherapy is carried out separately in each compartment, and the temperature detection component 31 can detect the temperature in each of the compartments and control the temperature, making the effects of the heating physiotherapy more uniform and stable.
The temperature control module 30 further comprises a remote control
+4 LU502025 unit 35, the remote control unit 35 1s connected to the second control unit 33 and the second power supply 34 and is configured for remotely controlling the temperature interval.

WIFI connection. The remote control unit 35 can adjust the preset temperature interval, for example, the temperature can be adjusted to a range from 39°C to 41°C or to a range from 35°C to 37°C. Temperature can be adjusted according to different users’ needs to meet the needs of heating physiotherapy at different temperatures.
À sweat absorbing member 15 is provided on one surface, in contact with skin, of the inner layer 12. The sweat absorbing member 15 is a detachable, replaceable sweat absorbing patch; the replaceable sweat absorbing patch consists of 96% cotton and 4% spandex.
